  1. reproduction involving meiosis and is important in many multicellular organisms.
  2. Chlamydomonas gametes are and consist of two types, though there is no genetic difference between the types.
  3. Maize is a (sporophyte contains both male and female parts) plant that exhibits alternation of , with a dominant stage and a stage.
  4. Sexual development in the nematode Caenorhabditis elegans is determined by the ratio of chromosomes to sets of .
  5. In the mode and mode of sex determination, gametes from the sex determine the sex of the progeny.
  6. Humans possess chromosomes: 22 pairs of and two chromosomes.
  7. of the X chromosomes (failure to segregate) during meiosis results in sex chromosome such as syndrome and syndrome.
  8. Other sex chromosome abnormalities include and aneuploidies.
  9. In humans, the region on the chromosome is necessary for male development.
  10. In mammalian females, one of the two X chromosomes in each cell is randomly during embryonic development and can be seen as a compact body.
  11. A female heterozygous for an X-resident gene may exhibit a phenotype.
  12. Sex determination in Drosophila depends on the of chromosomes to autosomes; loss of an X during development can result in a bisexual fly called a .
